10 meters? Generally 3 to 10 meters, even in the auxiliary road can also show, so don't worry about inaccuracy, car with civilian is a meaning, are satellites, authorized? This... Do you mean to buy genuine goods? There is no need, nor can I buy it.
We use the GPS receiver, handheld and vehicle, in addition to the model power, there is no difference, is the direct receipt of satellite signals, the use of satellites is a civilian satellite, should belong to the license.
The GPS satellite signal receiving chip, it can signal through the antenna and receive a plurality of GPS satellites broadcast, through the analysis of the signal will be able to know the distance between the car and the satellite, and know the exact position of the satellite in the center of the earth. Through complex calculation, you will know your position and time. Then you can find the location on the map and plan the way to the destination.
